Abstract: A rolling mill comprises a pair of an upper and a lower work roll having a small diameter which is as large as about 0.15 to 0.30 times the width of a metal sheet article to be rolled, a pair of an upper and a lower back-up roll, a pair of an upper and a lower intermediate roll disposed intermediate between the work roll pair and the back-up roll pair, work roll bending units and intermediate roll bending units imparting bending forces to the roll ends of the upper and lower work rolls and/or the roll ends of the upper and lower intermediate rolls respectively, roll shifting units capable of shifting the upper and lower intermediate rolls in axial directions opposite to each other, and drive units coupled to the associated ends of the upper and lower intermediate rolls to rotate the upper and lower work rolls at different peripheral speeds through the intermediate rolls. The directions of roll bending by the work roll bending units and/or the intermediate roll bending units and the relative movement of the body ends of the intermediate rolls relative to the widthwise ends of the sheet article caused by the roll shifting units are controlled thereby forming slight edge waves in the widthwise edge regions of the sheet article, so that, even when a high tension is applied to the sheet article during rolling with a high reduction ratio, occurrence of cracks in the widthwise ends of the sheet article is minimized to prevent breakage of the sheet article.

Abstract: In a process for the production of a grain-oriented electromagnetic steel strip, a slab is heated, hot-rolled, cold-rolled, and subjected to a decarburization annealing and secondary recrystallization annealing steps. Grain coarsening is likely to occur during the high temperature heating and remain in the final product as streaks. The secondary recrystallization is, therefore, incomplete due to the streaks. In order to remove this disadvantage, the work piece is subjected to at least two rolling passes, wherein the high circumferential speed roll of one pair of the rolls and the low circumferential speed roll of another pair of the rolls are arranged on the same side of the work piece.

Abstract: The present invention relates to methods of rolling metal articles and can be used to advantage in rolling sheet steel. This method envisages the rotation of drive and driven work rolls in opposite directions at a higher and a lower peripheral speeds, respectively. The chosen ratio between the peripheral speeds of the work rolls is less than the elongation of the article so that thereby the specified unit tension applied to the article at the exit section thereof is provided for with reference to the ultimate strength of the metal emerging from the rolls. This is conducive to increasing the maximum elongation of the article and reducing the roll force by a considerable amount with the constriction of the article in breadth at the same time.
